Green Lantern Corps #1 (New 52)

The issue begins with both Guy and John's troubles leading normal lives given the fact that they're publicly known to be super-heroes. Guy is denied a teaching position given that his presence could put students at risk and John's high standards for safety are scoffed at those willing to build his designs only if they will allow him to cut costs.
In need of some fresh air (so to speak) the pair take a trip to Oa and learn that two Green Lanterns have recently been killed in Sector 3599. Grabbing a team that includes Brik, Isamot Kol, Vandor, Hannu, and Sheriff Mardin set out to find the cause but are unprepared for what they find. A solid opener. Worth a look.
